Section 126: General Disciplines Relating to Penalty

Section 126 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

The Act's statement of how penalties should be imposed. Five sub-sections of protection, and a sixth that decides how much of it survives.

126(1): no penalty for minor breaches of tax regulations or procedural requirements, and in particular any omission or mistake in documentation which is easily rectifiable and made without fraudulent intent or gross negligence — a minor breach being one where the tax involved is less than five thousand rupees, and an omission or mistake easily rectifiable if it is an error apparent on the face of record. 126(2): the penalty shall depend on the facts and be commensurate with the degree and severity of the breach. 126(3): no penalty without an opportunity of being heard. 126(4): the order shall specify the nature of the breach and the applicable law under which the penalty is specified. 126(5): voluntary disclosure before discovery may be treated as a mitigating factor. 126(6): the section shall not apply where the penalty is a fixed sum or expressed as a fixed percentage.

Sub-section (6) first

It has to be read first, because it determines the section's reach.

"The provisions of this section shall not apply in such cases where the penalty specified under this Act is either a fixed sum or expressed as a fixed percentage."

What that excludes:

• s.122(1) — ₹10,000 or the amount involved, whichever is higher: an amount fixed by formula;
• s.122(1A) — an amount equivalent to the tax evaded or credit involved: a fixed percentage in substance;
• s.122(3) — up to ₹25,000;
• s.129(1) — 200% of tax, or 50% of value;
• s.74A(5) — 10% or ₹10,000, and 100%;
• s.123 — ₹100 per day, capped at ₹5,000.

What it leaves:

• s.125 — the general penalty, which "may extend to twenty-five thousand rupees". The words "may extend to" make it a maximum, not a fixed sum — so the quantum is discretionary and s.126 governs how the discretion is exercised;
• any other penalty expressed as a ceiling rather than a sum or percentage.

So section 126 has its sharpest application to section 125, and to the manner in which any discretionary penalty is arrived at. Section 125 →

The parts that survive regardless

Three sub-sections state principles that apply whether or not sub-section (6) bites, because they restate general law rather than create a discretion.

126(3) — no penalty without a hearing. This is natural justice, and it is reinforced by s.127 (a reasonable opportunity of being heard before a penalty order), s.129(4) (no penalty determined without an opportunity of being heard), s.130(4) (no confiscation or penalty order without one), and s.75(4) in adjudication.

126(4) — the order must specify the nature of the breach and the applicable law. An order imposing a penalty without identifying which provision was breached and under which provision the penalty is specified does not comply. It is the penalty analogue of the speaking-order requirement in s.75(6).

126(2) — proportionality. The penalty shall be commensurate with the degree and severity of the breach. Where the quantum is discretionary, this is the standard.

Sub-section (1): what a "minor breach" is

Two limbs, and they are different.

Limb one — a minor breach. Defined by Explanation (a): a breach where the amount of tax involved is less than five thousand rupees. A monetary test, with no intent element.

Limb two — an easily rectifiable omission or mistake in documentation. Defined by Explanation (b): an error apparent on the face of record — and qualified by the words in the sub-section, made without fraudulent intent or gross negligence.

So the second limb has no monetary ceiling. A documentation error of any size, if it is apparent on the face of the record and was made without fraudulent intent or gross negligence, is within it.

Examples that fit limb two: a transposed invoice number; a wrong GSTIN of the recipient corrected by amendment; a supply reported in the wrong table of GSTR-1; a HSN reported at the wrong digit level; a date typed wrongly on a delivery challan.

What does not fit: anything requiring evidence to establish, anything involving concealment, and anything the taxpayer knew of and left uncorrected.

Sub-section (5): voluntary disclosure

"When a person voluntarily discloses to an officer under this Act the circumstances of a breach of the tax law, regulation or procedural requirement prior to the discovery of the breach by the officer under this Act, the proper officer may consider this fact as a mitigating factor when quantifying a penalty for that person."

Two conditions: the disclosure must be voluntary, and it must come prior to the discovery of the breach by the officer.

How to make it count. Disclose in writing, identify the breach and the period, state what has been done to correct it, and keep the acknowledgement. A disclosure made after a scrutiny notice or an audit query on the same point is not prior to discovery.

And note what it is not. It is a mitigating factor in quantification, not an immunity. The immunities are elsewhere: s.73(5) / s.74A(8)(i) — pay before the notice and no penalty in a non-fraud case; s.74A(9)(i) — 15% in a fraud case. Those are far stronger than s.126(5), and they should be used first where a liability is genuinely identified. Section 74A penalty windows →

Using section 126 in a reply

1. Check whether s.126(6) applies. If the penalty proposed is a fixed sum or percentage, do not lead with s.126 — lead with s.75(13), the merits, and the characterisation.
2. Where the penalty is discretionary — s.125, or any penalty with a ceiling — plead s.126(2) proportionality with the facts: the amount involved, the absence of revenue loss, the promptness of correction.
3. Plead limb two of s.126(1) for documentation errors, showing the error was apparent on the face of the record and corrected.
4. Plead s.126(5) where the breach was disclosed voluntarily, with the disclosure letter annexed.
5. Take s.126(4) against an order that does not specify the nature of the breach and the provision.
6. Take s.126(3) where no hearing was given.

Key takeaways

• Section 126(6) disapplies the section where the penalty is a fixed sum or a fixed percentage — which excludes most of s.122 and s.129.
• Its sharpest application is to s.125, where the penalty "may extend to" ₹25,000.
• A minor breach is one where the tax involved is less than ₹5,000.
• An easily rectifiable documentation error is one apparent on the face of the record, made without fraudulent intent or gross negligence — with no monetary ceiling.
• 126(3) requires a hearing; 126(4) requires the order to specify the breach and the provision.
• 126(5) treats pre-discovery voluntary disclosure as a mitigating factor — weaker than the s.74A payment windows.
